Description

Technical Field

[0001] The utility model belongs to the technical field of equipment maintenance tooling, and more specifically relates to a quick-release tool for a driving sleeve of a mobile phone glass grinding machine. Background Art

[0002] During the production process of mobile phone glass, a grinding machine is required. For example, the mobile 3D mobile phone glass surface grinder disclosed in the patent with the publication number CN107855912A includes an upper disc and a lower disc. Both the upper disc and the lower disc rotate, and the rotation directions are opposite. The internal gear of the lower disc can be lifted and lowered.

[0003] The lifting structure is located inside the workbench. As Figure 3 shown, the lifting structure includes a driving sleeve and a fixed sleeve. The fixed sleeve is fixedly connected to the workbench. The driving sleeve is connected to the internal gear of the lower disc, and the driving sleeve is connected to a driving mechanism. The driving sleeve is slidably connected to the fixed sleeve in a lifting manner, that is, the driving mechanism drives the driving sleeve to realize the lifting and lowering of the internal gear.

[0004] Since grinding fluid is required when grinding mobile phone glass, and grinding hole particles are added to the grinding fluid. At present, since the grinding machine cannot be completely sealed, after the grinding machine works for a long time, the grinding fluid, the particles ground from the mobile phone glass, and the particles ground from the grinding disc will all enter the inside of the lifting mechanism, that is, between the driving sleeve and the fixed sleeve, resulting in difficult lifting or reduced lifting accuracy of the driving sleeve in the later stage, and it is necessary to disassemble the driving sleeve for cleaning.

[0005] Since the space between the driving sleeve and the fixed sleeve becomes a mixture of lubricating oil and particulate dust, when manually disassembling the driving sleeve after separating the driving sleeve from the driving mechanism, it is very laborious and time-consuming. Generally, the maintenance personnel drill under the workbench from below, then use a cushion block and a jack to support the lower end of the driving sleeve, and then slowly push out the driving sleeve from the fixed sleeve through the jack. However, due to the very limited space below, the manual driving space for the jack is limited, resulting in a very slow pushing-out process, and the maintenance personnel can only operate lying down, which is laborious and time-consuming. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a quick-release tool for a driving sleeve of a mobile phone glass grinding machine, which makes the disassembly more labor-saving and improves the disassembly efficiency of the driving sleeve.

[0007] To achieve the above object, the utility model provides the following technical solution: A quick-release tool for a grinding machine includes a first support plate and a second support plate. A support rod is arranged between the first support plate and the second support plate. A plurality of threaded holes are arranged on the fixed sleeve. A plurality of connection holes corresponding to the threaded holes are arranged on the first support plate. A through hole is arranged on the second support plate. The distance between the second support plate and the first support plate is the pressing distance. The second support plate is adjusted on the support rod to change the pressing distance.

[0008] Further, it further includes several cushion blocks. One end of each cushion block is provided with a positioning block, and positioning holes are provided at the other end of each cushion block and on the second support plate. The pressing distance is changed by the cushion blocks.

[0009] Further, a threaded section is provided on the support rod. The support rod passes through the second support plate, and nuts for threadedly connecting the support rod are provided on both sides of the second support plate. The pressing distance is changed by adjusting the nuts.

[0010] Further, the support rod is a telescopic rod, and a pin is provided between the telescopic sections of the telescopic rod. The pressing distance is changed by the telescopic rod.

[0011] Further, at least four support rods are provided.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: Remove the parts above the fixed sleeve and the driving sleeve, then separate the connection between the driving sleeve and the driving mechanism. Then place the first support plate on the top surface of the fixed sleeve. The driving sleeve passes through the through hole on the first support plate. Align the connection hole on the first support plate with the threaded hole on the fixed sleeve, and use bolts to fixedly connect the first support plate and the fixed sleeve. Then place a jack on the top surface of the driving sleeve, make the jack rod contact the second support plate, and then press down the driving sleeve through the jack. When the jack rod reaches the ejection limit, it retracts, and then adjust the pressing distance between the second support plate and the first support plate. After adjustment, use the jack to press down the driving sleeve again. After repeating many times, the driving sleeve is ejected and dropped from below the fixed sleeve, realizing the disassembly of the driving sleeve; Through the quick-release tool, the driving sleeve can be pressed down from above, and the space above the workbench is larger, providing enough space for the operation of the jack. The maintenance personnel can stand and operate, which is more labor-saving and improves the disassembly efficiency of the driving sleeve. BRIEF DESCRIPTION OF THE DRAWINGS
